Mr Alternatve,
I admire you, you work for what you want. I have seen some young guys (I presume you are 19+ ~ 20 years old) who just open their mouth and tell their parents that they want Xbox360, PS3, Ipods, iMacs, Macbooks etc... and their parents just go to the shop with them, sign and pick the items up...
Good to know nowadays, there are still aspiring young man like you.
To make things easier for us to help you, just let us know what is the maximum dollar that you can stretch. Face it... no one will sell you a working manual SLR or RF camera + lens with meter working, nice cosmetic, no physical abuse for S$100. If there are, probably he is a santa claus. (I met one last week who sold me a Nikon Nurvis APS camera for S$17, Thanks Samual... if u are reading).
I bought myself a Yashica MG-1 & an Olympus SP at S$40 each. Both meter not working, but still can shoot at fix shuttle speed for the MG-1 without battries. But it's not for beginners who want to pick up photography seriously with so much things to learn.
Something to share... I started learning about photography at 14 using my father's FE2. Though the years, I have never bought myself a SLR or RF camera. Until very recently I brought in the entire range of Cosina/Voigtlander product range and I bought myself a D60 for product shots. I can't say I am a good photographer, but I learn enough to make sure my shots turn out presentable.
So, the bottomline is:
1. Get something that is working and durable.
2. Set a realistic budget. For a start, I would say, $250 for a working FM2 body and $80 for a 35 or 50mm (might not be Nikon) lens.
If you just want to learn about shuttle-speed, aperture, focusing, I can lend you my Nikon FE2 with a 35mm lens for a few weeks. Then you can decide whether you want to get a SLR or stretch a little bit more to get a M6.
Regards,
Chii Fei
